IP CPU and MEDIA GATEWAY
The IPCA( )-U( ) ETU is an IP communication system that integrates voice
terminals with peer-to-peer connections over a Data Communication IP
Network (Intranet). When the Media Gateway [MG(8)-U( ) ETU] is installed,
the IPCA( )-U( ) ETU can communicate with the CPUI( )-U( ) ETU (Legacy
system) to accommodate both IP Multiline Terminals (D
term
IPK terminals) or
IP soft telephones and Legacy terminals (Electra Elite IPK terminals). The IP
Multiline Terminals and/or soft telephones are controlled by the IPCA( )-U( )
ETU. The Legacy terminals are controlled by the CPUI( )-U( ) ETU (Legacy
system). The MG(8)-U( ) ETU provides the actual speech path between the
two CPUs.
R2500 (R2.5) or higher is required for the CPUI( )-U( ) ETU.
With R3000 or higher, 12 Session Initiation Protocol (SIP) Trunks are
supported.
I-8
IP STATION (MEGACO)
The IAD(8)-U( ) ETU is an optional interface for Electra Elite IPK that
converts digital station ports to MEGACO IP station ports. An onboard 10/
100 Base-T connector provides a WAN/LAN connection. Voice or signaling
data from/to the IP stations is converted to IP frames and transmitted
through the Data Communication IP Intranet /Internet Network. This ETU
supports station-to-station direct RTP connections (peer-to-peer) for calls
between IP telephones.
R1500, R2500, or R3500 is required.
I-9
ISDN-BRI TRUNK CONNECTIONS
Integrated Service Digital Network - Basic Rate Interface (ISDN-BRI) is a
Public Switched Telephone Network (PSTN) service that provides two B
channels and a D channel (2B + D) for voice call trunking. The B channels
provide two CO/PBX connections. Caller ID is usually a standard feature on
ISDN-BRI provided trunks. Caller ID indication displays the calling party
telephone number on the LCD of the Multiline Terminal for CO incoming
calls. This interface provides voice communication path only.
With R1.03 or higher and BRT firmware 1.31 or higher, Caller ID Name is
supported on ISDN-BRI trunks when the Telco provides this ability.
With R4000 or higher and BRT firmware 3.00 or higher, DID can be
supported for ISDN-BRI trunks.
